Can`t agree with either LH or Lighter, this was typical US smaltz, a British or European film depicting wars of the same era would not have indulged in such guff, the Irish Sergeant was so much stage Irish as to be laughable.
I wouldn`t admit to being a slouch on the Us Civil War as I have quite a large library of books on the war, also numerous documentaries including Ken Burns brilliant doucumentary on the war, far and away the best series ever done on it.
The only saving grace the film had was the realistic battle scenes, the dialogue was sick-bag naterial.
